The PANDA plan space visualizer is a tool for debugging and analyzing the planning process of PANDA.

The PANDA planning system can be configured in such a way that it creates an output file containing the explored search space. This file serves as input for PANDA plan space visualizer, which can display various information that is important for debugging: The search space corresponds to a tree data structure; its nodes and leafs can be selected, such that its partial plans are displayed graphically. In clearly arranged tables, information about the current partial plan is displayed, such as the sequence of modifications leading to it and the flaws that were resolved by the respective modifications.
